BACKGROUND OF THE INVENTION 1. Field Of The Invention The present invention relates generally to the games or machines of skill art, and more particularly to a novel target type machine in which an operator achieves step-by-step success by aligning on a visible screen a maneuverable projected cross hairs image with a moving target image to the degree required and manually momentarily closing a switch and circuit while the images are in the aligned relation, ultimate success resulting from accomplishing the aforesaid a required number of times in an allowed time interval.

2. Description Of The Prior Art Many games and machines of skill have been devised. Hundreds of thousands are in operation throughout the world. Entertainment is an important function of life for many reasons, hence, novel machines of skill requiring agility of eyes and hands are in constant demand. However, the applicants are aware of no machines of skill operating as that presently disclosed.

SUMMARY OF THE INVENTION The present novel machine for demonstrating the skills of an operator comprises, in brief, a cabinet within which is mounted a slide projector or the like, a screen, and means for carrying projected images to the screen. Each image includes a target, some differen'tly located. Electrically actuated mechanisms are provided for moving the projector continuously in a random type manner during play so that an image projected on the screen has such movement. A projection bulb and a transparency holder and lens unit are also operatively mounted in the cabinet for projecting a cross hairs image onto the screen on the images or pictures. A handle with a manually actuatable switch is located for manipulation by a user of the machine, said handle being operatively mechanically connected to the cross hairs image projection unit for movement thereof to, in turn, move the projected cross hairs image about the screen for purposes of aligning it with the target on each picture. The handle switch energizes mechanism for changing the picture projected on the screen which is operative to momentarily close a circuit only if pressed with the cross hairs image aligned with the target image to the degree of incidence required. A score is made for each successful picture change. The machine is coin or slug operated and includes a timer limiting the period of play.

Objects of the present invention are to provide a novel machine of skill designed to test the combined eye and hand agilities of the user, which is highly entertaining, which meets the public demand for machines of skill, which is constructed for long term operation with minimum maintenance, which provides access for inspection, removal and replacement of parts or elements and for other purposes, and which otherwise fulfills the objects and advantages sought for such a machine of skill, which appears from the specification below taken with the accompanying drawings.

DESCRIPTION OF THE PREFERRED EMBODIMENT Referring to the drawings more particularly by reference characters, the letter A indicates generally a machine incorporating the principles of the present invention. The machine A includes an upright type cabinet or housing 1 of the configuration clearly shown in the drawings. The cabinet 1, in general, comprises two cooperative housings 5 and 6, the latter telescoping into the former. The housing 5 includes a floor or base secured by screws or the like on and to two longitudinal beams 151 which also mounts adjustable feet 152. Side panels 153 and 154 of the cross section shown in FIG. 2 are secured to the floor 150 and beams 151 by screws and the like. A top panel 155 is secured to the side panels 153 and 154 by screws or the like. In the top panel 155 is a hot air vent 72. A rear access door 157 is maintained in position by a rotatable key operated lock 158. A front deck type access lid 159 is rotatably mounted on a hinge 160 and maintained against unauthorized movement by a rotatable key actuated lock 161. An upper inset frame 3 supporting a viewing screen 2 held in position by brackets 4 and the like is provided (FIGS. 3 and 4). Supported beneath the screen 2 is an elongated illuminated title screen 9 used for advertising the particular pictures in the machine A.

The housing 6 slides into the housing 5 from the front of the latter, and includes side panels 163 and 164, a horizontal panel 165 spaced above the floor 150 of the housing 5, a rear vertical panel 166, an upper front angled panel 167, and a lower inset front skirt panel 168. The aforesaid panels are secured together with screws or the like.

For projecting an image on the screen 2, a rearwardly facing projector 10 is located within the machine A and may be a rotary type slide projector or a suitable continuous film unit, as desired. The projector is secured to a base frame 11, which is pivotally connected for generally horizontal movement adjacent one end thereof to a stationary supporting channel beam 12 by means ofa pivot pin 13 (FIGS. 3 and 12). The channel beam 12 is welded or otherwise secured to parallel end plates 7 which are mounted to the side panels 163 and 164 by screws 8 or the like.

The pivot pin 13 extends through a hole in the base frame 11 and is welded thereto at 171 (FIG. 12). The pivot pin 13 also extends through a hole 170 in the upper disposed leg 172 of the channel beam 12, said hole 170 being of a little greater diameter than that of the pin 13 and being of enlarged hemispherical form in the lower part receiving a complementarily contoured collar 173 maintained in position by a compression spring 174 and cotter pin 175. Thus, the projector 10 can be rotated about the pin 13 as an axis and/or tilted or pivoted up and down about the edges of the leg 172 as indicated at B and C.

The other end of the frame 11, hence, of the projector 10, is supported by the upper end of an adjustable connecting rod 14 through a bracket 57 welded to the frame 11 and pivotably connected to the rod 14 by bolt unit 176. The connecting rod 14 is pivotally attached at its lower end to an integral off-center pin 201 of an eccentric 65 by a ball and socket connection 195 permitting limited wobbly movement of the upper end of the rod 14. The eccentric 65 is secured to for rotation by a driven pin 194 of the gear unit 196 ofa gear motor 15, the motor 197 of which is operatively mounted to the gear unit 196 by a sleeve structure 198 enclosing a driven shaft. The gear unit 196 is secured by screws to a vertical flanged plate 200, which, in turn, is secured to the horizontal panel 165 by suitable bolt and nut assemblies 202 (FIGS. 3 and 8). it is clear that energization of the motor 197 through the gear unit 196 and eccentric 65 effects up and down movement of the connecting rod 14, and hence, up and down movement of the rear end of the projector 10.

For effecting pivotal movement of the frame 1], hence, the projector 10, about the pin 13, there are provided a second gear motor 17, and an eccentric 65 with integral off-center pin 20]. To the pin 20] is pivotally attached a connecting rod 18 by a ball and socket joint 195', the other end thereof being secured to the frame 11 by a suitable bracket. Thus, with both gear motors 15 and 17 energized and driving the eccentrics 65 and 65 at different speeds, the frame 11 and projector 10 will move in a random pattern, which can be varied by changing motor speeds or gear ratios.

In front of the projector 10 is an angularly disposed mirror 18 which is secured to the panel 166 of the housing 6 by suitable brackets 19 and screws or the like. A mirror 18 in an operating machine is 4 X 4 inches. Rearwardly of the partition panel 166 and supported on the floor panel 150 of the housing 5 by adjustable nut and bolt assemblies 22 is a mirror panel 21 to which is secured a mirror 20, which may be 7 /2 X 7 /2 inches. located to receive an image from the projector 10 by way of the mirror 18, as indicated by the broken lines 207 and 208. the image traveling from the projector 10 to the mirror 18 through an opening 211 in the panel 166. The image from the projector 10 then travels to a third mirror 23, which may be X 26 inches, secured to a mirror board 24 mounted to the side walls 153 and 154 of the housing 5 by suitable brackets 212, as indicated by the broken line 209, thence to the screen 2 as indicated by the broken line 210, arrows showing the direction of travel of the image from the projector 10 to the viewing screen 2. The image thus projected on the viewing screen 2 is in constant random motion, since the projector 10 is so moved, as is explained above.

It is to be understood that the disclosed projector 10 is of the well known carrousel type made by Eastman Kodak Company, which includes an electric motor rotated carriage carrying the pictures, as will appear from the circuitry description.

A second projection system throws on the screen 2 a maneuverable cross hairs image130, which includes in vertical alignment with and beneath the pivot pin 13 a projection bulb 25, which may be 500 watts, mounted on a plate 26 supported on and secured to the panel 165 by adjustable nut and bolt assemblies 27. A vertically disposed plate 30 is located at one side of the projection bulb 25 and supports a mirror 28 mounted on a mirror plate 213 welded to the plate 30 at an angle less than (FIGS. 3 and 9). The plate 30 also supports at one side a film retaining plate 29 for removably receiving transparencies 33 and at the other side as by welding an internally threaded collar 81 receiving an externally threaded sleeve 36 which supports a lens 34 at the free end thereof by means of a threaded clamp ring 35. The plate 30-is secured as by welding to the rear end of an elongated right angle bracket 31, which, in turn, is pivotally secured near said rear end to the support bar 12 by a pivot pin 32. The pivot pin 32, in similar manner to the pivot pin 13, extends through a hole in the bracket 31 and is welded thereto at 179 (FIG. 12). The pivot pin 32 also extends through a hole 180 in the lower disposed leg 181 of the channel beam 12, said hole being of a little greater diameter than that of the pin 32 and being of enlarged hemispherical form in the upper part receiving a complementarily contoured collar 182 maintained in position by a compres sion spring 183 and cotter pin 184. Thus, the plate 30 and its supported elements can be rotated about the axis of the pin 32 and/or tilted or pivoted up and down about the edges of the leg 181 as indicated at D and E. Hence, the cross hairs image on a transparency 33 is projected by a light beam from the bulb 25 traveling therefrom along the path indicated by the broken line segments 220, 221, 222 to the lens 34 (FIG. 9).

Rearwardly of the lens 34 is an angularly disposed mirror 230, which may be 4 X 4 inches, which is supported by a bracket 231 and suitable screws from the panel 166. Below the mirror 230 is a mirror 37, as 7 /2 X 7 /2 inches, secured to a plate 38 mounted on the floor panel by adjustable nut and bolt assemblies 38'. Thus, the cross hairs image 130,-after passing through the lens 34, reaches the viewing screen 2 via the broken line segments 223, 224, 225 and 226.

The position of the cross hairs image 130 on the viewing screen 2 is controlled by an operator of the machine A through manipulation of a control handle or wobble stick 40, which is mounted at the front of the housing 6 and extends through an opening in the panel 159, as illustrated. The handle 40 swivels in a ball and socket unit 41 comprising a ball 39 secured to the lower portion of the handle 40 and a socket 39 secured, as by the welding shown, to a frame 42. The frame 42 includes a transverse support member 185 mounted at its ends to the side panels 163 and 164 by screws 186 through end flanges 187. Spaced short longitudinal members 188 are welded to the member 185 and to a plate 189 secured by screws to the front panel 167. The socket 39 is welded at diametrically spaced points to the members 188. For further stability, parallel transverse short support members 190 are welded to the socket 39 at diametrical points and to the members 188. Manifestly, other supporting structures can be used. A bumper unit 43 is mounted on the handle 40 below the ball 39 including an annular resilient ring 43' which limits swivel movement thereof through striking the adjacent members of the frame 42. A diametrically extending cross plate member 44 is secured by means of a nut 44' to the lower end of the handle 40, being spaced from the bumper unit 43 by a collar 45 (FIGS. 3, 5 and 6). Threaded into one end of the cross plate member 44 is a mounting screw 46, to the outer end of which is secured the upper end of a flexible sturdy web strap 47 by means of a screw 48 and a lock nut 49. The lower end of the strap 47 is secured to the upper end of the bracket 31 by a nut and bolt assembly 235. To the opposite end of the cross plate member 44 is secured a ball joint 50. The ball joint 50 is, in turn, secured to a second ball joint 52 by means of a threaded connecting pin 51. The ball joint 52 is threadedly mounted to a plate 53 secured to the front panel 167 by screws. This just described ball joint arrangement secures the end of cross plate 44 so that any movement of the control handle 40 transmits a like movement to all attached components, and thus controls the movement of the projected cross hairs image 130 on the screen 2 in a like manner. It will be noted that the panel 159 can be raised readily without removing the handle 40, the latter swiveling as the former is pivoted into raised position, the hole in the former being adequate.

To succeed in projecting the next picture on the screen 2 and to register a score, the operator must maneuver the cross hairs image 130 by manipulation of the control handle 40 until it coincides to a required degree with a bull's eye image 131 provided in projected image or picture, and while maintaining such required coincidence close an electric switch 54 mounted in the top of the handle 40 in position for ready depression of its actuating button by a finger of such operator (FIGS. 3 and 4). The actuating structure includes a curved insulating board or member 56 of fiber glass or other insulative material secured to the forward end of the bracket 57 by suitable screws or the like for movement with the frame 11. Electric contact point members 55, shown as modified screws, are mounted on the insulating board 56, there being a separate member for each differently disposed target 131. Each member 55 is threadedly disposed in a mounting nut 64 secured in position against the board 56 by a washer 64' of plastic or other suitable material adhesively secured to the board 56. An electrical lead is soldered to the side of the nut 64. Each member 55 includes an integral reduced contact point 55 which extends through the board 56. For closing an operating circuit through the members 55 there is provided a movable actuator comprising a steel ball 58 disposed in a plastic sleeve 59 having a rounded edge 59' which facilitates sliding over protruding contact points 55'. The ball 58 is biased towards the board 56 and the contact points 55 bya compression spring 60 mounted in a well in one end of a pin 61, said one end extending into the plastic sleeve 59 for support of the latter. The other end of the pin 61 is insulatively mounted to a bar 62 by means of opposed fiber insulating washers 63 maintained in position by nuts 63'. A compression spring 240 about the pin 61 biases the plastic sleeve 59 towards and into engagement with the board 56. An electric lead is secured to the end of the pin 61 by a screw. The bar 62 is secured by nut and bolt assemblies 62 or the like to the bracket 31 for movement therewith, this bracket 31 as described above having the same movement as the projected cross hairs image 130. Contact between the concerned contact point 55' and the ball 58 is made when the cross hairs image and the target image 131 are in the required percentage of alignment set for the concerned target. The effective size of the contact area is adjustable by threading the contact member 55 in or out of the mounting nut 64. As the point 55' is moved inwardly from a position substantially flush with the board 56, the ball 58 as it is maneuvered over the surface of the board 56 will strike the concerned point 55 sooner on the increasing radius. The effective contact circle is increased, hence, the circuit can be closed without perfect coincidence of the cross hairs image 130 with the concerned target 131. With the point 55 substantially flush with the board 56, the contact area is reduced to the diameter of the point 55', hence, almost perfect alignment of the cross hairs image 130 with the concerned target 131 is required. This, of course, requires the greatest skill to achieve picture change.

When the switch 54 is closed with the ball 58 in engagement with a contact point 55, a solenoid 113 is energized which pulls a lever 68 downward to depress the standard operating button on the side of the projector 10 to change the picture, thus projecting the next image on the screen 2. The operator repeats his efforts.

The projection bulb 25 is cooled by air from a funnel 69 supplied by a blower 70 which are bolted or otherwise secured to the plate (FIG. 3). Air intake is provided through a filter 71 behind the front panel 167 and hot airis exhausted through a vent 72.

The above-mentioned title screen 9 comprises a frame 73 which is mounted above the panel 166 and is secured to the opposed side panels 153 and 154 by suitable brackets and screws or the like (FIGS. 3 and 7). A fluorescent lamp 74 for illumination of the title screen is mounted in standard sockets secured to the ends of the frame 73 and is replaceable from the rear of the machine A upon removal of a snap-on type cover plate 75. A screen member 76 is frictionally held in position between plastic sheets 77 and 78 by means of screws 80 at each end thereof which extend through the front of the frame 73, holes in the plastic sheet 77, and threadedly engage the plastic sheet 78, as is clear from FIG. 7. Rubber strips 79 provide the necessary resiliency for effective reception and retention of the title screen member 76. The title screen 76 may be removed and replaced from the front of the machine A after pivotally raising the panel 159 by grasping the lower edge thereof and withdrawing the same, removal and replacement being facilitated by the rounded lower edge of the plastic sheet 78.

To more completely understand the operation of the machine A, the electrical circuitry is illustrated in FIG. 13 and is described in the following paragraphs. The

electrical power enters the machine A at line plug 81 and ground. The plug 81 is attached to wire 82 which runs through the entire machine A supplying one side of 110 volt circuit to all components of the electrical system. The ground wire 83 is attached to the machine cabinet 1 at a point 84, to a ballast 85, and to the bulb 74 which illuminates the title screen 9. Plug 81 is also attached to a line 86, which is the control line side of the circuit and is attached to the various components of the machine A as shown in FIG. 13 and as described below. Line 82 is connected to a transformer 87 which reduces the voltage to that required to protect the handle operated switch 54. To start operation of the machine A, a switch 88 is provided which is operated by a coin. The switch 88 is attached to the line 86 by a line 89, and is a component part of a coin rejector, motor timer and counter assembly 90. When the coin switch 88 is energized, current is fed to a counter 103 and through a line 97 to a relay 92 and a relay point 98, thence through line 99 to energize a coil 100 in relay 91.

When relay 91 is energized, current flows through a point 104 and through a line 106 to the projection lamp 25, the gear motors and 17, a contact point 111 in a relay 112, the transformer 87, and a contact point 115 in the relay 96. A contact point 105 in the relay 91 is also energized and current flows through a line 107 to a disconnect plug 109 on a projector 10 and to a projector projection lamp 116. Current is also fed to a coil 118 in a timer relay 93 and to a point 123 in the relay 93, thence to blower 70, which cools the inside of the cabinet 1.

With all component parts energized and now in operation to play the machine A, the control handle switch 54 is closed and low voltage current from the transformer 87 passes through a line 124 to switch 54 and through a line 125 to a coil 126 on a noise maker or knocker relay 112, closing point 111, current passing through a line 127 to a point 128 in a relay 94.

The current passes through a line 129 to the contact points 55. At this time, if the cross hairs image 130 is aligned tothe required degree with the target image 131 on the viewing screen 2 (FIGS. 1 and 4), current will pass through the concerned point 55 to the ball 58. This current then passes through a line 132 to a coil 122 in the relay 96. At the time the relay 96 is energized, current passes through a contact point 115 and through a line 133 to an electric bell 114 and a solenoid 113. When these components are energized, the signal bell 114 rings, indicating a bulls eye i.e., a change to the next picture and a score, and the solenoid 113 depresses an actuating button on the projector 10, causing the carrousel thereof to index, which places a new target picture on the screen 2, this image containing a target and a registered score, At the same time current is in the line 127, current is fed to a coil 121 in a relay 95, and, if the target and pointer cross hairs images 130 and 131 are not operatively aligned, contact point 134 closes and feeds current into a line 135 energizing a coil 120, opening points 128, thus eliminating current to the line 127 and points 111 and forcing the operator to take a second shot with the control switch 54 in order to register a score. Thus, the switch 54 cannot be held operatively depressed while maneuvering the cross hairs image 130. This method of firing the machine A to change the picture and register a score can continue until the timer motor 102 completes its cycle and opens the coin switch 88, thus ending the play. 7

At the time the play ends, the coil in the relay 91 is deenergized and the points 104 and are opened, thus stopping the operation of the cross hairs image projection lamp 25, picture oscillating gear motors 15 and 17, and eliminating current to the hand switch 54. The projector machine 10 remains on for a predetermined length of time to allow the operator to view the last image in a stationary position on the screen 2 and to see the projected score. In order to accomplish this, the control circuit of the timer relay 93 is closed at contact point 136 in the relay 91, thus throwing the relay 93 into the energized position and closing the point 123 which feeds line 107, thereby holding projector machine 10 in the operating state. When viewing time is completed, the timer relay 93 returns to normal position and point 137 closes, thus energizing the line 138 and current passes through a stop switch of the machine 10 to a line 139, energizing a coil 119 in a relay 92, thus closing points and 142 thereby energizing projector motor 117 and projector advance solenoid 113 causing the carrousel of the machine 10 to rotate, which continues until stop switch 110 contact a carrousel stop 145, thus opening point 137 and stopping current flowing through line 139 to the relay 92 causing the points 140 and 142 to open, stopping the projector motor 117 and deenergizing carrousel advance solenoid 113, thus returning all working parts in the machine A to the start positions and it is ready for another play.

The present novel machine A is shown coin or slug energized, but such mechanism can be replaced by an on-off switch, as for home use. Further, as is indicated above, while a slide projector 10 is dislosed, the present invention is adaptable to moving pictures.

It is apparent that there have been provided a novel machine and a play method which fulfill the objects and advantages sought therefor. I
